I googled for you:
http://www.warriorforum.com/main-internet-marketing-discussion-forum/267429-accepting-payment-via-bank-transfer.htmlYes, wire transfers are as reversible as anything else. Any movie that shows the spy with the laptop wiring funds for the super-secret microchip is building on a completely false premise. Anything banking is all on a web of trust, and if the originating bank wants their money back they will get it back. In addition, for this "service", banks often route the wire transfer through several other banks that are part of their network of good ol' boys that take a cut of the transfer - you can have $50 or more taken out of your money transfer from mystery banks along the way.
No banking payments should be be trusted at face value; consider every payment as trustworthy as if it was sent from foreign hackers who have compromised online banking accounts and are looking to liquidate stolen funds, unless the payer can prove otherwise.
